How do you manage your firewalld linux configuration in Ansible?

To do this you have to:

• Open the dnf.conf file.
• Add the exclude directive in the [main] section.
• Save the changes.

The difference between them is that in v8, the RHCSA level tasks using RHEL 8 and ansible 2.8 whereas in v9, RHEL 9 is used to task RHCSA level along with ansible-core 2.12+.

One way to do that is by getting the output with register and storing it in a local file. Then make the python script read the file. Take this information and store it into a variable.

For a first ansible playbook you should start with a small and simple task, till you get familiar with the syntax. Always try using in-built modules instead of writing custom codes. You should use version control to track any changes made to ansible.

Ansible-lint indicates that the playbook will fail while upgrading to a newer version of Ansible. However, spotter determines the target version of Ansible and is responsible for retrieving the source version from the system, to help you to be certain about which version the upgrade happened and to which one and manage all fixes according to that.
